I think it is not nearly as good as the Acer Iconia, at least through the speakers.

 

Compared to Xoom which blast the music away from you, Xoom's speaker sound quality is still better than the TF. The TF volume is really weak including using the headphone.

 

i was watching outside yesterday on the porch and had to turn it up pretty loud. it was ok until the very top % and it would be too much and sound like crap. The zoom was better in this category

 

Download Equalizer, a free app, from the Android Market. I think that this will solve your sound problems, both volume and quality.

 

I tested both side by side.. The Xoom is not louder it just has more bass. So in a way you can say it sounds louder.
